"Inspection was very professional, Jonathan is a great person, ready to answer any of your questions and give you a pro advice what and when you should expect with the property you're buying. I was really happy that he agreed to perform inspection on Saturday, so i didn't lose any of my working hours at my job. And pricing..it's more than reasonable for the service quality we received. 100% recommended. Thank you, Jonathan!"

"They were an extremely honest and quick moving company. From the agent that scheduled our appointments to the inspectors that showed up, they were all above and beyond. The word "thorough" is an understatement. I wouldnt be surprised if that man inspected every single INDIVIDUAL brick on that house. He was kind, well spoken and seemed to genuinely care about what he was doing. Because of their incredible work ethic, they ended up saving us from making the worst decision of our lives. As I stated, he was brutally (but still professionally) honest with us... And it was a breath of fresh air to have somebody SO educated on our side to not only show us the facts but to also share their personal/knowledgeable opinions with us. I would recommend this company to ANYONE who is looking to purchase a home. These guys seriously won't let you down."

"Mark Pierce was very helpful and thorough. We are moving from TX to NC and could not be there for the inspection but Mark called and went over everything he found concerning with us. We used them for the home inspection, water test and radon test and were very happy with their service."

"Daniel was extremely thorough and Professional. I had a few questions and concerns about buying this home, Daniel was personable and willing to make sure I understood everything. He walked through things that would need to be done and (when I ask) gave an estimated time frame I would want to have it done by. I had a VA Loan so he did the water test required for that too. Best $ I spent in this whole money grabbing home buying process. I highly recommend him for your home inspection and will use again myself If I need to.  Richard, Lake Lure"

FAQs for radon gas testing projects in Marion, NC

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
